[FR] Support Unity Server Builds

[gabetoth-alder]

Our mobile project has a multiplayer server which will run on linux. We build the server with Target Platform set to linux and Server Build ticked on the Build Settings window in Unity Editor on Windows.

When the server starts the attached log message is seen. server_crash.txt This part at the end hints that the libs aren't loaded:

Details:

• Firebase .so files are in the build
• using .NET 4.x and unity 2020.3.31f1
• the server fails and crashes with this when built with mono or il2cpp backend
• this happens on AWS GameLift instances - https://aws.amazon.com/amazon-linux-ami/2018.03-release-notes/ (only info I found)
• this doesn't happen on Ubuntu 20.04.3 LTS (our test server), runs as expected
• this doesn't happen when we build for Windows platform, runs as expected.

[gabetoth-alder]

Update:

I managed to reproduce the crash with a vanilla empty project with just firebase auth added to it and a MonoBehaviour with just the dependency checking

[gabetoth-alder]

Update:

I ticked Load on startup for the .so files in editor and after that I got some more logs:

/lib64/libm.so.6 exist, but the version is mismatching, AL2 is using 2.26 and some other components have dependencies for it libc++.so doesn't even exists anywhere, my guess if I fix the first one it might fix this one to.

1. Did it start to happen after you upgrade or this just happen after you add Firebase into your server project?
2. Could you elaborate what you mean by We build the server with Target Platform set to linux and Server Build ticked on the Build Settings window in Unity Editor on Windows.? Are you build the instance on Linux and run it on Windows?
3. Could you detailed the reproduction steps and let us know in which environment that it works and which not?

Thanks, Shawn

Hey @gabetoth-alder. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

1. It happened with every version we tried.
2. we built it on windows for linux. (windows editor set to standalone linux target platform)

[chadrockey]

I'm also seeing this issue, seems whenever File -> Build Settings is set to Dedicated Server under Platform, the needed files are packaged but can't load when the application tries to run.

I setup an anonymous login project and still see the issue.

Source code (attached to the Light):

    // Start is called before the first frame update
    void Start()
    {
        Firebase.Auth.FirebaseAuth auth = Firebase.Auth.FirebaseAuth.DefaultInstance;

        auth.SignInAnonymouslyAsync().ContinueWith(task => {
        if (task.IsCanceled) {
            Debug.LogError("SignInAnonymouslyAsync was canceled.");
            return;
        }
        if (task.IsFaulted) {
            Debug.LogError("SignInAnonymouslyAsync encountered an error: " + task.Exception);
            return;
        }

        Firebase.Auth.FirebaseUser newUser = task.Result;
        Debug.LogFormat("User signed in successfully: {0} ({1})",
            newUser.DisplayName, newUser.UserId);
        });
    }

Error log when run on Linux Server.  Windows server outputs very similar errors:

@gabetoth-alder Were you able to find a resolution?

[chadrockey]

@gabetoth-alder @chkuang-g I don't know why our Windows tests of this same Dedicated Server build were failing, but I found a fix for Linux dedicated servers.

They need sudo apt-get install libsecret-1-dev to be installed.

After this I was able to proof of concept anonymous authorization followed by reading a Firestore document.

[gabetoth-alder]

@chadrockey

Were you able to find a resolution?

Not yet. I managed to have my server run firebase-free, since only game logic runs on it, but for later it would be nice to make it work.

Sounds great! I will test it this week hopefully, I'm working on other things right now!

[dev-cmurphy]

Hi! Just to say I have the same issue on my side. sudo apt-get install libsecret-1-dev did not work for me.

I'm running automated tests with GameCI on a GitHub Actions Ubuntu free instance.

[chkuang-g]

@chadrockey

Thank you for finding the solution by running sudo apt-get install libsecret-1-dev on the dedicated server. Let me talk to the team and see if this is expected on Linux and to update the document.

@gabetoth-alder Please let us know if this solution works for you.

@dev-cmurphy For game.ci related discussion, please use this thread https://github.com/firebase/firebase-unity-sdk/issues/449. Let's separate them until we can verify if they are the same issue. Thank you :)

Please do not mark as stale, would really like an official resolution for running with dedicated server builds

[gabetoth-alder]

Sorry for my late update, I got the following results:

For AWS GameLift we have an install.sh script:

sudo yum -y update
sudo yum -y install libsecret-1-dev

The update runs as expected, but the install libsecret-1-dev fails:

No package libsecret-1-dev available.
Error: Nothing to do

I had my servers working on ubuntu instances without any problem, but GameLift uses 'AMAZON_LINUX_2' inhouse OS.

[AlmostMatt]

Is this a case of the libsecret package having a different name on different OS? I found this page which suggests that libsecret-devel is available on Amazon Linux 2 http://213.146.141.13/package/details/OracleLinux7/x86_64/x86-64/libsecret/0.18.6

I confirm that I was able to install the package, I will check the server logs later, I my server crashed for another unrelated issue

Edit: It didn't work, server log:

Hi all,

Just for clarity the Firebase Unity SDK doesn't officially support server builds. We don't build and test this scenario either, so we don't have a full working knowledge of the trails you're blazing. Please upvote this issue so that we can prioritize it on our roadmap.

The more information that you can provide to use the better as maybe something will jump out at us as something that we've encountered in other tested scenarios.

Unless I'm wrong this seems to be a missing dependency issue attempting to resolve libraries on various flavors of Linux. Potentially the Amazon versions of libsecret are incompatible with the ones that the Firebase SDK requires, and though the Firebase .so files are found they can't be loaded in conjunction with the platform's libraries.

We mainly test against Ubuntu and I believe that Amazon Linux is either CentOS or Fedora, depending on which version of Amazon Linux you're using. There could be a mismatch there?

@gabetoth-alder, in your latest attempt was there any output beyond Unable to preload the following plugins:? Is there more debug information that can be enabled?

Thanks!

Yes it would be great, it can have a lot of benefits.

Probably there is something missing in the Amazon Linux.

I cannot add anything else at this point, my server is built to work without firebase (I moved stuff needed to the client, which is is... ok for the current project, but creates limits), so it doesn't crash or produce any more issues. Before that it crashed at the dependency check.

[DellaBitta]

Ok, I'm going to rework this ticket as a feature request for server builds, and keep the ticket open so we can prioritize it properly.

Please upvote this issue if you're looking to use server builds with our SDK. Thanks!

Any updates on this? I am running into this issue with servers running on Unitys Multiplay.

[DannyKrendel]

Having the same issue with Unity Multiplay.

Have you found a solution?

[Jeffry15]

After some research, I found a workaround that works for Ubuntu Server 23.10, which may work for other Linux systems.

Possibly why the error happens

Firebase .so files is compiled code, and it expects to see some authentication package, this may change depending on what you build for, but the expected package is for desktop editions with a screen, so it's not preinstalled, once installed, they load, but you get an error usually with a log from libsecret (or you dont but Firebase has an exception still), but the error's root cause is dbus (Linux's graphics package) which isn't logged, you can view the error by running: dbus-run-session -- ./<ServerBuildNameHere> you can also see what it wants by navigating to your server build folder/<ServerBuildName>_Data/Plugins (where the firebase.so files are) and then entering ldd * (note that some of them are linked by virtual memory, to the file location is not specified, but only the packages that say 'not found' are missing packages), you might find that afterwards FirebaseCPPApp afterwards says not found, which is likely a visual bug, it is found and loaded when you launch the build, it's also in the logs of the Unity Server build, near the top it says 'preloaded FirebaseApp or preloaded FirebaseAuth all the incompatibility of Unity Server builds for Linux mostly stems from missing packages, or that the missing packages bring errors themselfs.

libsecret-1-0 is one of Linux's authentication package, however for different systems, there may different packages for libsecret available, the one that works with me is libsecret-1-0 and I do have libsecret-1-dev, but it's not there for dev-cmurphy's system (or maybe they haven't updated their package manager yet), systems using Amazon AWS may want libsecret-devel, to see all the available versions in your system, enter apt install libsecret-*, then see the packages listed with a prefix of 'libsecret-' and enter n to not install these packages if you don't want them.

What to do

• Try these commands, it's what worked for me: sudo apt update -y; sudo apt install dbus dbus-x11 gnome-keyring libsecret-* -y; sudo mkdir -p ~/.cache; sudo mkdir -p ~/.local/share/keyrings; sudo export $(dbus-launch); sudo eval "$(printf '\n' | gnome-keyring-daemon --unlock)"; sudo eval "$(printf '\n' | /usr/bin/gnome-keyring-daemon --start)"; sudo dbus-update-activation-environment --all; sudo apt remove dbus dbus-x11 gnome-keyring libsecret-* -y; sudo apt install libsecret-1-0 -y; sudo reboot if your in a Linux system that uses gnome, note that it's changing the service for user passwords, if there are non-root users in your system, do it in a different environment and see if theres any security issues. It also leaves some unused packages, use apt autoremove to remove them.

If your using docker, note that gnome keyring requires root access to the host machine, for security reasons, I recomend running docker run --privileged <your params and image> and do these commands then save the image while the container is running with docker commit <ContainerIdOrName> <NewImageName>, and run the new saved image instead, you can view all images with docker images -a, it should run without --privileged afterwards. Also note that docker forces --privileged to be off next time the container is started, so if you reboot it, it doesn't have root access.

• Try running the server build with root as a test, if it works then it's a permissions issue. Root isn't affected by deny permissions.

• If you have xinitrc, it's been reported to cause some issues with dbus which is used by libsecret, there may be issues with other packages, try troubleshooting with minimal packages to avoid other error factors temporarily, then test it in your system.

• If you get an error about a version of libstdc++ not being installed, update your system or downgrade your Firebase version, libstdc++ is the c++ compiler, which is what compiled Firebase .so files, if they were compiled with a version higher than your version of your c++ compiler, you get the error, but it's not a simple apt install, many critical system packages are compiled with .so, so it doesn't update it, and if you remove then try installing it, your system won't boot nor will it update it.

Also note that Firebase sometimes gives their own exception if you do too many failed attempts, it will clearly say it in the logs though as a System.Exception.

If this doesn't work, you can wait for Firebase to support it or troubleshoot it with the information mentioned, I think there's only 2 steps:

• Make sure nothing except FirebaseCppApp says not found in the Firebase .so files
• Fix any problems with the Firebase dependencies, if you don't understand them you can try googling the problem.

This is rough but it's something to go off of for others, and possibly help making support for Unity server builds, hope this helps!

+1000 for this. Clients should never touch the database, or even know anything about it, or where it is, or what it is. Game server must have full access, everything client wants / needs flows through game server (plus maybe a separate web service for account creation / auth before connecting to game server). No Firebase libs should be in the client builds.

No idea why you wouldn't have started from that perspective.

[jayman2989]

Jumping in here to reup and reaffirm support for this request! Our dedicated servers should absolutely be in control of the data writing, and not entrusting that to clients.
